Abstract
Numerical interaction model of reinforced concrete slab and subsoil was created in ANSYS. Input data for numerical analysis were obtained during experimental loading test of reinforced concrete slab. Loading test was performed using unique experimental equipment constructed in the area of Faculty of Civil Engineering, VŠB-TU Ostrava. Analysis of interaction of reinforced concrete slab with subsoil was solved with application of inhomogeneous half-space. Application of inhomogeneous half-space allows better capture the subsoil behaviour and its increasing modulus of deformability with increasing depth of subsoil model. Homogeneous half-space this takes no account. Reinforced concrete slab was cracked during an experiment. The effect of cracks was also taken into account in the numerical model of reinforced concrete slab using derived modulus of elasticity of cracked concrete. Values calculated by all types of interaction models were compared with values measured during the loading test of reinforced concrete slab.
